This after action report (AAR) focuses on the response of Portland’s Neighborhood Emergency Team (“NET”)volunteers and community organizations in the Portland Community Organizations Active in Disaster network (“PDX COAD”). The primary audience for this AAR includes NET volunteers, NET Team Leaders, PBEM Program Managers, and COAD member organizations.

AAR Definitions and Acronyms
In addition to the usual complement of government acronyms, we present a few important distinctions between cooling facilities:Cite error: Closing </ref> missing for <ref> tag]]
From June 25 to 29, a heat dome parked itself over the Portland metropolitan area and obliterated temperature records all over the Pacific Northwest. Portland experienced three consecutive days of abnormally high heat reaching 108, 112, and 116 degrees. Dr. Vivek Shandas with Portland State University recorded a sidewalk surface temperature at SE Woodstock and 92nd Avenue that hit 180 degrees, high enough for third degree burns at direct skin contact.[1]
As of December 1, 2021, the County Medical Examiner confirmed 73 heat related deaths in Multnomah County from the June heatwave. Previously, between 2010 and June 2021, Multnomah County ever recorded only two heat illness (hyperthermia) deaths.[2] Combining the 73 with deaths elsewhere in Oregon, Washington, Idaho and British Columbia, the heat dome led to the deaths of approximately 500 people. Most of the persons who died were older, white, and socially isolated or lived alone and without central air conditioning. Their deaths were preventable.
Emergency managers in the region mobilized for heatwave preparations only three days before June 25. Since more preparation lead time can improve response capacity, it is worth noting factors that possibly contributed to curtailed lead time in June:
- Regional response inexperience with temperature extremes at this level. For example, at the time, PBEM did not have Operational Guidelines in place for an event like the June heat dome.
Daily maximum temperatures in Portland, 1938 - 2021. The three isolated points above the fray represent June 26 - 28, 2021. Click to enlarge.[3] - Conservative weather forecasts leading up to the heat event. A June 21 NWS weather briefing indicated a high confidence forecast of temperatures above 90° starting June 25 with a 50% chance of temperatures hitting 100° that weekend. Concerning, but not highly alarming. Email traffic at PBEM confirms professionals in the region took the prospective heat seriously and worked to plan for it; but until June 22, some doubts remained Portland would reach temperatures over 100° that weekend. Solid indications from NWS that temperatures would exceed 100° on Sunday and Monday in addition to Friday and Saturday do not appear in email traffic until the morning of June 23. Even on the days that followed, the forecasted hottest day and temperatures changed.
- A community safety net already stretched and frayed by COVID-19. The pandemic has led to increased social isolation (a factor in heat illness deaths) and houselessness.
- A possible boil water notice looming over much of the west coast. Regional emergency managers were planning for a prospective interruption of the supply of sodium hypochlorite.[4] Utilities use sodium hypochlorite to disinfect drinking water and wastewater. An equipment failure at a chlorine manufacturer in Longview resulted in a shortage of the disinfectant impacting the entire west coast. From June 14 to 28, utilities and emergency managers braced for the possibility of running out. That did not happen. But the implications of a short chlorine supply were serious: it could mean asking Portlanders to curtail water use and possibly a regional boil water notice. This incident held the attention and resources of emergency managers right up to the June heatwave.
In other words, the June heat dome was a growing emergency inside matryoshka dolls of emergencies.
PBEM moved the ECC into partial activation on June 23. That day, the COAD Coordinator began mobilizing community outreach efforts via PDX COAD on June 23, sending warnings and instructions to partner CBOs and calling some of them individually to check in. In a meeting the next day, Multnomah County decided to open two cooling centers beginning on Friday, June 25: the Oregon Convention Center and Sunrise Center (and later added the Arbor Lodge Shelter). A bulletin to NETs that day put them on standby for volunteering, but online shift signups were not available for sending to NETs until 11:00 the next day (June 24). Multnomah County Emergency Management took responsibility for the online signups, but posted eight hour shifts instead of the four hour shifts customarily offered to volunteers. The short notice combined with the long shifts later factored into low volunteer availability. On June 25, Portland’s Chief Administrator’s Office requested help from City employees to fill shift gaps.
Throughout the heatwave, staffing needs at cooling centers changed as the City and County expanded cooling center operating hours. The shift additions, though essential, necessitated repeated requests to volunteers for staffing many times in the midst of the emergency.
On June 24, Multnomah County requested assistance from the City reaching out to residents at apartment buildings by phone; Maybelle Center for Community made a similar request the same day to the COAD Coordinator. NET Coordinators posted an electronic signup to recruit phone welfare check volunteers late the following evening.
Portland NET and COAD responded throughout the heatwave, and through the demobilization of cooling centers on July 2.

Volunteer Recruitment: Communications Timeline
The volunteer signup service used by PBEM and Multnomah County time stamps every volunteer signup. This data can be placed on a timeline with the date/time PBEM sends volunteer recruitment communications (email or social media post). The table below indicates when, to who, and how government contacts released volunteer recruitment and COAD messaging. The magenta numbers in the left table column correspond to the graph on the right margin. The comparison makes the most sense side by side; so, for those interested in this data, we recommend clicking and opening the graph in a separate window and scanning down the table to note which messages were most effective recruiting volunteers.
Is this information useful? Probable answer is: ¯\_(ツ)_/¯. But it is interesting! If nothing else, the graph demonstrates the importance of the first flush of communications for recruitments, since that is the communication which will garner the most volunteers.

June 2021 Heat Dome Volunteer Response
The deployment period ran from 06/25 until 07/02, with volunteers needed primarily to staff cooling centers. The response required 718 shifts spread over 5,639 volunteer hours (of which 74% were filled). Of that number, 81 NETs volunteered for 121 shifts and contributed 920 hours. For a full accounting and breakdown of volunteer shifts and hours, please view the June Appendix.
NETs volunteered at Arbor Lodge, Alder Commons, and the Oregon Convention Center. Additionally, they assisted at the JOHS Logistics Center. Misting stations were not yet included in the response strategy.

Late/Overnight shifts: 180 (25%) of available June shifts were late night or overnight shifts. 136 of these shifts (76%) were filled. In hours, late/overnight shifts constituted a total of 1,586 available hours and volunteers signed up to cover 1,200 (76%) of those hours. According to preliminary County data, the Cooling Shelters served around 1,400 overnight guests over the course the June heat event.
Volunteer Response Outcomes
The map above next page indicates the locations of NET volunteer service, as well as guest headcounts.
The COAD Coordinator sent four safety alert messages to member CBOs from Wednesday to Sunday with heat safety messaging, social media graphics, print and post flyers, resources in eight languages, and action items for CBOs to respond to. The COAD Coordinator also facilitated supply drops (consisting of water, cooling towels, and other items) to mutual aid groups and six low-income residential buildings.
NET volunteers phoned 211 vulnerable contacts with heat safety tips, cooling center information, and connections to rides to cooling centers. Some of these contacts were provided by Multnomah County, but COAD partners provided most of the information.
The June Appendix includes more detail on the resources Multnomah County deployed during the event.
